概要
近年RISC-V移行の流れが盛んになってきている。
https://eetimes.itmedia.co.jp/ee/articles/2506/27/news072.html
Chromiumもその例に漏れずM139からRISC-Vでのビルドが可能になっている。(139.0.7231.0からRISC-Vのsysrootをインストールできるようになっている ので、未確認ではあるがこのバージョンからRISC-V向けビルドが可能なはずである)
ここではM143においてRISC-V向けにビルドする方法を解説する。
前提
- Chromiumのソースコードをfetch済みである
- fetch後以下のコマンドで143.0.7486.1にcheckoutすること
git checkout 143.0.7486.1
gclient sync
ビルド手順
依存関係・sysrootのインストール
以下のコマンドで依存関係及びdebian sysrootをインストールする。
cd src
./build/install-build-deps.sh
./build/linux/sysroot_scripts/install-sysroot.py --arch=riscv64
サンドボックス用RISC-Vパッチの適用
sandbox周りで以下のようなエラーが発生する。
